It is hypothesized that increased intraabdominal pressure (IAP) may be a cause of preeclampsia. There is, however, a paucity of clinical data regarding IAP in preeclamptics. We evaluated and compared the IAP and its effects on organ functions, in normotensive and preeclamptic patients. Material and methods Previously healthy non‐laboring patients with a singleton pregnancy scheduled for elective cesarean section under subarachnoid block were enrolled (preeclamptic and normotensive; n = 29 each). IAP was measured using an indwelling Foley catheter, and compared in both cohorts at four predefined time points: just before subarachnoid block, immediately after the onset of sensory block to T 6 dermatomal level, just after surgery, and 2 hours later. In addition, the presence of organ dysfunction for respiratory, cardiovascular, renal, hepatic, hematopoietic and central nervous systems were evaluated for association with IAP. Results Although age, body mass index, gravidity, parity, serum bilirubin, serum creatinine, PaO 2 /FiO 2 ratio and Glasgow coma score of the preeclamptic and normotensive patients were similar, the mean blood pressure was significantly higher ( P < 0.001), the period of gestation less ( P = 0.003) and the platelet count lower ( P = 0.020) in the former. The IAP was significantly higher in the preeclamptic group at all four time points: respectively, 15.1 (1.0) vs 14.2 (0.9) mm Hg ( P = 0.002); 14.9 (0.9) vs 14.1 (1.0) mm Hg ( P = 0.002), 10.4 (1.0) vs 9.5 (1.3) mm Hg ( P = 0.008) and 10.2 (0.8) vs 9.2 (1.2) mm Hg ( P = 0.001). There was no correlation between the IAP and various organ dysfunctions. Conclusions Preeclampsia is associated with a significantly higher IAP in patients undergoing a cesarean section. The clinical relevance of this finding needs further investigation.
